Embodiment

Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.

A kind of USB interface device that the utility model embodiment provides with rotating mechanism, this USB interface device is made up of USB body 1, mainboard 2, USB 3, this mainboard 2 be positioned at this USB body 1 above, by technologies such as screw, buckle or welding this mainboard 2 is fixedlyed connected with this USB body 1.The top of described USB body 1 is connected with this USB 3, and this USB 3 is connected with the top of USB body 1 but can be by not locked, and this USB 3 is rotatable, and described USB 3 can be used as socket and is connected with subscriber equipment, realizes transfer of data.This subscriber equipment is the subscriber equipment with USB interface, includes but not limited to portable terminal, terminal, digital camera, scanner, joystick, vision facilities, printer, keyboard, mouse.As shown in Figure 1, for this has the front of the USB interface device of rotating mechanism, on the drain pan of the USB of USB interface device body 1, be fixed with two incorgruous shell fragments 11, by technologies such as screw, buckle or welding that two incorgruous shell fragment 11 nails are dead on the drain pan of USB body 1, this shell fragment 11 is five metals, and meeting springing owing to the effect of external force, be connected by a brace between two incorgruous shell fragments 11, promptly, described two incorgruous shell fragment 11 integrated shell fragments 11, these two incorgruous shell fragments 11 are at the dorsal part of this USB 3.There is a connecting hole 31 centre at this USB 3, by this connecting hole 31 USB body 1 and USB 3 is connected, this connecting hole 31 is an axial hole, USB connecting line 32 passes this connecting hole 31, two of this USB connecting line 32 is connected with respectively and is fixed on mainboard 2 and the USB 3, thereby realizes the transfer of data between mainboard 2 and the USB 3.This has the inside of the data card of rotating mechanism, and as shown in Figure 2, the inside of connecting hole 31 is gear 33, and this gear 33 is the part of USB 3, and in the inside of USB 3, when USB 3 rotations, this gear 33 also can rotate accordingly.The teeth groove of this gear 33 is a circular recess, this gear 33 is linked together by a plurality of circular recesss and is formed, when the USB that this is had gear 33 3 packs on the drain pan of USB body 1, just can be with two incorgruous shell fragments 11 interlock mutually on the drain pan of this gear 33 and USB body 1, make two incorgruous shell fragments be fixed in the same circular recess of gear 33, when USB 3 is rotated, can be rotated by driven gear 33, two incorgruous shell fragments 11 interlock mutually on the drain pan of this gear 33 and USB body 1, gear 33 revolutions are crossed a tooth, two incorgruous shell fragments 11 will be because of the effect of gear 33 these external force springing once, at this moment, by the interlock of gear 33 and two incorgruous shell fragments 11, USB 3 just can rotate normally, when being connected USB 3 on the USB body 1, this USB 3 axially can be rotated.At USB 3 during to anticlockwise, the right shell fragment in two incorgruous shell fragments 11 will work, after this USB head turns over a gear, at this moment the right shell fragment in these two incorgruous shell fragments 11 can be positioned at current location with this USB 3, when not having external force to be applied on this USB 3 again, promptly do not have external force to be applied on the gear 33, at this moment USB 3 will be in move left and right, has the USB interface device of rotating mechanism to use this; Same, at USB 3 during to right rotation, left side shell fragment in two incorgruous shell fragments 11 will work, after this USB head turns over a gear, at this moment the left side shell fragment in these two incorgruous shell fragments 11 can be positioned at current location with this USB 3, when not having external force to be applied on the USB 3 again, does not promptly have external force to be applied on the gear 33, at this moment USB 3 will be in move left and right, has the USB interface device of rotating mechanism to use this.After this USB interface device with rotating mechanism assembled, as shown in Figure 3 and Figure 4, this USB 3 can rotate to the inside of this data card, also can this USB 3 be stashed by rotation.As seen; the utility model is by with two incorgruous shell fragments 11 interlock mutually on the drain pan of gear 33 and USB body 1; can realize the rotation of USB 3; after USB 3 turns over a gear; just the location once, thereby improved the practicality of USB interface device, and the ease for use that has increased data card; and beautified outward appearance, saved USB protection lid.

The above only is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be looked protection scope of the present invention.
